Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521990, here are decompositions:

31 + 33521959 = 33521990
37 + 33521953 = 33521990
97 + 33521893 = 33521990
127 + 33521863 = 33521990
163 + 33521827 = 33521990
193 + 33521797 = 33521990
277 + 33521713 = 33521990
367 + 33521623 = 33521990

Showing the first eight; more decompositions exist.
